what is difference between Providence and Fate according to Lady Philosophy

Providence, a difficult concept to understand, is explained roughly as the reason of God ordering the universe. It is the overall plan that God has for the world, even when Fate (the ordering of events on earth) seems to be disordered. Lady Philosophy concedes that this is indeed a mystery, for everything takes place simultaneously for God, and we in our temporal world cannot understand this.

True happiness (in some translations Felicity) is the pursuit of God through intellectual and spiritual means. It is considered the supreme good by Boethius, and the only good worth pursuing. All earthly goods are false goods, and only our spirit and intellect can lead us to the true good of the soul: God.
